At the end of his first overseas trip as Secretary of State, John Kerry acknowledged that despite the continued diplomacy and tough sanctions being leveled against Iran, the regime continues to get closer to possessing a nuclear weapon.

“Lines have been drawn before and they’ve been passed,” Kerry said. “That’s why the president has been so definitive this time. This is a very challenging moment with great risks and stakes for everybody because the region will be far less stable and far more threatened if Iran were to have a nuclear weapon.”

Kerry sat down with ABC News’ Martha Raddatz in Qatar as his first overseas trip as President Obama’s secretary of state wound down.
